We are in the process of importing our water mains into an asset management system. The system rejects any line segments with an arc/curve (example below). I think these were imported ~15 - 20 years ago from CAD. Trying to research a way to query out these features that will need to be updated to not contain arc segments. I looked through some Data Reviewer options but did not yield any results yet. We are on Desktop 10.3.1.
You can convert the data to a shapefile which will automatically turn the arcs into polylines which would work in either ArcMap or Pro whichever you have access to.
I believe Pro 2.3 (not sure it's in any earlier releases) has a way to field calculate if there are curves in polyline feature classes if you want to know which lines will be converted.
